To open a package you double-click on the package name in the package Tree. This will open the package to reveal the components as children.
To add the PIC16C54 double-click on the PICMicros package icon and select PIC16C54 from the components in the list.
Your screen should now look like this.
The PIC16C54 has now been selected as the current component. You will notice the Properties editor has been populated with properties for the PIC16C54. There are four properties. Type, Orientation, Filename and WatchDog.
Type and Orientation are properties common to all components and are read only in the property editor. Type is the name of the component in the component package and obviously has the value of PIC16C54. Orientation determines which of four directions that component is facing and can only be changed by the component rotation tools, to be discussed later.
Filename and Watchdog are special PIC16C54 properties and are editable in the properties editor. Have a look at the PICMICROS component specification for more information.
Filename locates the source code to be executed by the PIC. Two file formats are available, LST and HEX. LST is the MPLAB LST file generated when compiling source in MPLAB or any other development environment that supports MPLAB LST files. HEX is an Intel format HEX file containing the PIC execution code. Note that Debug facilities are only available for LST files.
